Warranty terms
12 year warranty for speakers and 2 year war-
ranty for power amplifiers and electronics (from
purchase date) on materials and work time, with
the exception of damage caused by incorrect use
or electrical or mechanical overload. An original
copy of our invoice is required as the warranty
document. This warranty is exclusively valid for
loudspeakers, power amplifiers and electronics
that have been purchased from Teufel for pri-
vate use by end customers. The warranty is not
valid for loudspeakers, power amplifiers and elec-
tronics that the end user has purchased from a
different distributor. If the Teufel product is sold
on privately, the warranty may be transferred to
the purchaser,providing that the original proof of
purchase is also transferred.
Returns
Teufel grants an 8 week right to exchange or re-
turn the appliance for a reimbursement of the
purchase sum paid.
The return of individual components in a set is
only possible if these components are also offered
for sale separately by Lautsprecher Teufel. If one
or more components are returned, any price dis-
count given by Lautsprecher Teufel on all compo-
nents in a set as part of the price for the set is
waived. For the components returned, customers
shall therefore be refunded only the difference
between the set price and the purchase price of
the individual components that they retain. The
economic outcome for customers is as if they had
bought the remaining components at the indivi-
dual price from the outset.
You will find more information about returns on
the return form enclosed with the shipment or
online in the support area of our www.teufel.de
website.
If you need to return an item, do not act without
the prior agreement of Lautsprecher Teufel.

Safety information
Important: Please read through these operating instructions
very carefully. It is essential that you take note of all of the sa-
fety information and operating instructions before switching
on the appliance. Please keep these operating instructions in a
safe place for future reference.
Important: Please read the operating instructions. You should
also follow all instructions for start-up and ongoing use.
Information on cleaning: Please do not attempt to clean the
appliance using household chemicals, as this could damage the
surface. Simply use a dry cloth. Disconnect the appliance from
the mains before cleaning.
Caution – moisture and sunlight: Never operate the appliance
in damp rooms, i.e. close to baths, showers, wash basins, drains,
damp cellars or swimming pools; never use it where there
is moisture. Never expose the speakers to high air humidity
and avoid direct sunlight. Do not expose device to dripping or
splashing water. Do not place objects filled with liquids, such as
vases on the device.
Information on location: Do not use the appliance unsecured
in vehicles, in unstable places, on wobbly tripods or furniture or
supports that are too small. The speakers could fall and cause
damage to people, including yourself. Speakers, particularly if
positioned on stands or on the TV/monitor, may fall and cause
damage due to their weight, even if they have been positioned
securely and basically protected against falling, as a result
of external influences (pulling on the cable, tripping over the
cable, unintentional physical contact). This also applies to wall
supports that have been attached inappropriately or incorrect-
ly to walls that may not be capable of supporting their weight.
Only use suitable wall brackets for mounting. Make sure that you
know how much weight the walls can bear. The appliance must
not be placed near sources of heat. This includes radiators and
heaters, ovens and other appliances that emit heat(e.g. ampli-
fiers). Sources of heat, such as fan heaters or candles, should
not be placed on the speakers.
For ventilation: Slits and openings in the case have been provi-
ded for ventilation. Their purpose is to guarantee reliable ope-
ration and to prevent the appliance from overheating. These
openings must not be blocked or covered, including by placing
the appliance on a bed, sofa,carpet or other soft surface. Do not
place any newspapers or table cloths, etc. on the appliance. The
cooling plate of the amplifier electronics must not be covered
or exposed to direct sunlight. Additional active cooling of the
appliance is generally not permitted.
Electrical supply: The subwoofer must only be supplied from a
power source with the correct voltage as specified on the iden-
tification label. If you are unsure about the electricity supply
in your home, please contact us or your electricity supplier for
more information.The device must be grounded. Please only use
the appropriate power cable for connecting to the power sock-
et. Do not modify the power cable under any circumstances! You
must comply with regulations regarding polarity and grounding.
The power socket of the device will only accept a 3-pin power
plug. Make sure the power switch is in the “off ” position before
connecting or disconnecting the device.
Information on wiring: Please place the supply cable flat and
flush to the wall and floor. Cables that are laid loosely represent
a risk of tripping. This could also result in interference and cau-
se the sound to be disrupted. The electricity supply cable should
be laid so that it is not likely to be stepped on or squashed from
the sides or above by heavy objects. Damaged cables must be
replaced. Pay particular attention to the cable/plug connection,
the mains socket and the cable output from the subwoofer. The
power supply cable and the cables that connect the speakers
should be checked regularly for insulation faults or breaks. If a
fault is discovered, the appliance and the cabling must be dis-
connected from the mains immediately and the defective cable
must be replaced.
Duringperiodswithoutuse:Removethesubwoofer’spowersup-
plycablefromthesocketforlongerperiodsofabsenceornon-use.
During thunderstorms: In order to avoid damage caused by
lightning strikes, the appliance should be switched off and also
detached from the mains socket as soon as a thunderstorm is
expected.
Risk of overload: You should not overload wall sockets, ex-
tension cables or integrated appliance sockets, because this
could potentially lead to short circuits and even fires. You
should also avoid turning up the volume very high on the re-
levant amplifier, especially if you have increased the bass using
the bass control, the volume button or one of the deep bass
boost switches.
Foreign bodies and liquids: Foreign bodies and liquids must
not get into the appliance via its openings under any circum-
stances, as they could come into contact with parts carrying
high voltages, which could then cause short circuits and fires.
Therefore do not spill any liquids of any kind on the appliance.
Troubleshooting: Do not attempt to repair the appliance your-
self. Contact our service department first for authorisation if
you think that you can repair the fault yourself. Otherwise the
appliance must be sent to our service department’s address.
Transport: The appliance should be transported using a hand
truck. Great care must be taken during transport. Please note
that uneven surfaces, sudden stopping or inappropriate exerti-
on of force may cause the hand truck and the load to fall over.
Information on spare parts: Lautsprecher Teufel will provide
you with spare parts during the warranty period. Your warranty
will not be invalidated if you replace the parts yourself on-site
using Lautsprecher Teufel spare parts.
Unusual sounds: If any unusual sounds occur during use or the
sound becomes distorted, the speaker output must be reduced
immediately so that the system plays an undistorted sound.
Connecting and changing the fuse: Disconnect the mains plug.
A faulty fuse should only be changed for one of the same type.
Information on volume: Loud noises can damage hearing. Sud-
den high pressure may be created, particularly if a “subwoofer”
in “Standby/Auto On” mode is switched on by a bass impulse at
full volume. In addition to physical damage, please be aware of
possible psychological consequences. Children and pets require
particular care. If necessary, set the volume control of your
signal source appliance to the lowest level. At high volumes, al-
ways keep a certain distance from the appliance and never have
your ears right next to the speaker.
Please read the following
safety information carefully.
Risk of suffocation – keep
packaging materials (e.g. the
plastic lm) out of the reach and
sight of children.
Risk of electrocution – do not
leave children unsupervised with
electrical appliances!
In case of emergency:
If any of the following occur
disconnect the appliance from
the mains and consult our tech-
nicians:
4If the plug or line is damaged
4If foreign bodies or liquid
enters the appliance
4If the appliance has been
in direct contact with rain
or other water
4If the appliance does not
play, even though you have
followed the instructions for
use
4If the appliance has been
dropped or damaged in some
other way
We cannot accept any responsi-
bility for incidences that occur
because safety information has
not been adhered to.

Introduction LT 2
Dear Lautsprecher Teufel customer,
Thank you very much for buying speakers from
Lautsprecher Teufel.
You have purchased a very high-performance
speaker system: Lautsprecher Teufel speaker
systems are equipped with high quality compon-
ents and are manufactured carefully. We recom-
mend the LT 2 for providing sound in rooms up
to 35 m2in size. In this respect, only the acou-
stically utilised area is taken into consideration.
Neighbouring spaces such as eating areas can be
ignored. Particularly high rooms over 3.50 metres
should be multiplied by a factor of 1.5. The set can
also be used in larger spaces where there are low
requirements for continuing volume.
Before operation please read these instruc-
tions carefully and store them in a safe place for
future reference. If you have any further
questions, please contact our engineers on
Tel. [phone] or use the email contact-
form on our website www.teufel.eu. Please have
your invoice number ready so that we can deal
with your query as efficiently and as quickly as
possible.
BEFORE contacting us with a question, please read
the “Problems and solutions” section on Page 14
of these operating instructions and visit our web-
site(www.teufel.eu) where you will find answers to
many questions in “FAQ/Support”.
Please refer to our safety information on Page 4
of these operating instructions and only use the
speakers once you have read the safety informa-
tion.

Unpacking · Items delivered
Please check in advance that
the system is complete.
Please note:
Please keep the boxes for at
least the eight-week return
period, as we can ONLY repay
the full purchase price if the
products are returned in the
ORIGINAL PACKAGING in
which they were supplied!
Warning:
Inappropriate replacement of
the battery may cause explosion.
Replace only with batteries of
same type. Do not expose the
battery to excessive heat such as
sunshine or re.
If you plan to not use the device
for a longer period of time:
remove the batteries from
remote control and store them
appropriately to prevent possible
damage from leaking.
Information:
The ve passive speakers in the
set – no matter whether they
are the satellite FCRs or column
FRs – are equipped with the
same speaker chassis and are
technically identical; the column
speakers simply have an inte-
grated base that can be ignored
acoustically.
The speakers can be used in the
front, centre or rear depending
on the room requirements. We do
however recommend that they
are used in pairs – for example
both column speakers TOGETHER
either for front OR rear sound.

The LT 2 is preconfigured and ready to play as a 5.1
configuration set. Such a set plays back all sound
tracks contained on DVDs and already provides an
excellent home cinema experience. It is suited to
connecting to all common AV receivers – no matter
whether they are designed as 5.1, 6.1 or 7.1 systems.
Teufel banana plug
These high-quality Teufel
all-round plugs enable you
to connect your speakersto
an amplifier or receiver in a
cost-effective and reliable
way. A stable screw grip
firmly holds all cables with a diameter up to 4 mm.
Permanently elastic spring contacts and genuine
gold-plating guarantees plug connections with
very low resistance. Supplied in pairs, one plug
red and the other black.

General information on configuration
It is easy to integrate the Teufel LT 2 harmonious-
ly into your living room thanks to its clear design
lines and slimline shape. However, there are some
configuration rules for home-cinema systems
that need to be observed in order to produce the
ideal sound from the Teufel speaker set.
For home-cinema systems, we recommend con-
centrating on the area really used – i.e. the room
(area) where the TV/screen and seats are actually
located. The TV/screen should be positioned as
centrally as possible to the listening location.
The recommended set-up (on the following
pages), represents the best possible arrange-
ment for perfect multichannel playback at home.
Your available space, your partner or furniture
may not always permit such ideal placement. Try
to meet as many requirements as possible. Small
variations are not a problem. Modern AV receivers
offer numerous options for compensating elec-
tronically for any compromises in the set up. Ge-
nerally speaking, the following rule always applies:
You can always use our recommendations to ex-
periment with what works best acoustically and
optically. Let your ears(and eyes) decide!
Setting up the 5.1 configuration
Centre
As the centre plays back all voice information, in-
cluding the actors’ dialogues, the centre speaker
satellite FCR must be as central as possible to the
listening position or located above the TV/screen
so that the sound and image make up a harmo-
nious unit.
For this the centre can be set up on the cradle
supplied or fixed directly to the wall using the ap-
propriate screws/rawlplugs.
Front
Using the old stereo tradition (distance to li-
stener = distance between the left and right
speaker), the front speakers are set up next to
the TV/screen at the same distance to left and
right (column speaker L 220 FR) or fixed to the
wall (satellite L 220 FCR). If the column speakers
have to be placed further out, you can easily turn
them inwards and towards the listening location.
Thanks to their magnetic screening the two front
speakers can even be used near a traditional ca-
thode ray TV.
The following applies if the satellite FCR speakers
are placed on the wall or shelves: Select a set-up
height of between 40 centimetres and 1.20 me-
tres(lower edge). It is important that the centre
and front speakers are approximately in a line, or
possibly even on a slight arc to the TV. Otherwise
the homogeneity of the playback may vary with
run time differences. Setting the speakers up in
this way allows them to deliver their full sound
potential.
Tip:
The sound from the column
speakers benets from being
near a wall.

Setting up the 5.1 configuration
We recommend placing the
subwoofer in the front grey
area.
Select position area A or B.
We recommend placing the
rear speakers in the rear grey
area.
Subwoofer
The location of a subwoofer with a recommended
cut-off frequency of 110 Hz can be freely selected
and does not affect the other speakers. Place-
ment within a straight line between the two front
satellites is ideal. But you can also try it out at
any other location in the room. Thanks to its ma-
gnetic screening, it can also be placed near the
TV. We must, however, advise you not to use it as a
“TV table”as the subwoofer’s vibration may cause
the TV to “wander” – with potentially damaging
consequences to the appliance and users.
Rear
The rear speakers should be set up to the left and
right either to the side or behind the liste-
ning location – ideally at the same height as the
front speakers, e.g. on a shelf or directly on the
wall. The speakers can be fixed higher than the
front speakers (up to 2-10m); but we advise you
not to locate them lower.
We always recommend that the distance between
the rear speakers and the listening location is
over 1.00 m. But if you (have to) sit closer, please
ensure that the front of the speaker is not poin-
ting directly at you but rather angle the speakers
more into the room. Or create a greater distance
by positioning the speakers higher than 1.20m.

We recommend placing the

If you add an additional pair of L 220 FCR speakers
to your 5.1 complete set (refer to Page 7 of these
instructions) you can also use the complete per-
formance range of a 7.1 AV receiver and therefore
use the LT 2 as a 7.1 home cinema system.
Front · Centre · Subwoofer · Rear(side)
The speakers are set up in the same way as for the
5.1 set. Please read the description in “Setting up
the 5.1 configuration” on Pages 8 and 9 of these
instructions.
Rear Centre
The ideal placement of a 7.1 system assumes that
the rear effect speaker(rear side) is fixed to the
sidewall next to the listening location and the
rear centre speakers are on the back wall; always
at a height of 0.40–2.10 metres. The same height
as the rear side speakers would be perfect. If you
use the FCR satellites as the rear centre, you can
fix these to the wall horizontally or vertically.
If you visualise the set up graphically and link
the four rear speakers with lines you will ideal-
ly get a trapezoid with equal length arms. Each
arm should be longer than 1.00 metre. As soon as
the arms have different lengths or the four rear
speakers are set at different heights, you can ba-
lance this asymmetry by entering the distances
of the individual speakers in the AV receiver’s
speaker setup.

Connection
The LT2 in the 5.1 configuration with an active
subwoofer can be connected to any normal Dol-
by Digital/DTS 5.1/6.1/7.1 AV receiver. For a 7.1 AV
receiver you do not use the rear centre socket(s).
If you already have a modern 7.1 AV receiver you
can expand your theatre LT 2 with two additional
L 220 FCR satellites to make a 7.1 home cinema
set.
Connect the front, centre and rear speakers to a
5.1 AV receiver as per the diagram in Fig. 1.
Connect the subwoofer output (Sub Out) of your
Dolby Digital/DTS-AV receiver via a mono-cinch
cable with the right Line Input of the subwoofer
as per the drawing in Fig. 2.
The left input(Line Input L) remains unoccupied. A
Y-adapter is required to use both of the subwoo-
fer inputs(refer to Accessories, Page 7).

Settings · Operating elements(remote control)
Setting up the AV receiver
For your home cinema system LT2 with active sub-
woofer, select the “small” or “normal”(not “large”)
setting in the bass/speaker setup of the AV recei-
ver for the satellites – this guarantees that the
satellites can be fully loaded and the subwoofer
and front speakers harmonise perfectly with
each other.
The subwoofer must be set to “On” in the bass/
speaker setup on the receiver. The appropriate
cut-off frequency in this set-up for the LT 2 is 110
Hz(100/120/150 Hz are also possible).
Setting up the subwoofer
When operating the system on the AV receiver, the
frequency control on the subwoofer/remote con-
trol must be set to “Maximum” = “140 Hz” becau-
se the cut-off frequency is set by the AV receiver
– its settings are dominant.
Modern AV receivers set the subwoofer phase
correctly when adjusting the distance of the
subwoofer from the listening location during
“speaker setup” – so the phase controller on the
subwoofer itself should be left in the “0°” positi-
on. For older AV receivers or appliances without
an option to compensate for the distance of the
subwoofer, the following applies:
With the phase controller, you can adjust the sub-
woofer to the satellites such that the speaker
membranes vibrate in the same direction in the
cut-off frequency range. If the phase is set incor-
rectly, the bass may be weakened or cancelled.
For a subwoofer position between the front spea-
kers, we recommend “0°”(grey field in the illus-
tration on Page 8), for a position near the liste-
ning location“180°”. If the subwoofer is in another
location, the “180°” setting can balance out the
reduced bass playback. Set the phase controller
appropriately to get the strongest bass playback.
The volume setting of the subwoofer may be
slightly different when playing back music com-
pared with home cinema sound, depending on the
recording quality and mixing. Whereas a massive
bass element predominates on DVDs with lar-
ge quantities of special effects, for music the
desired level is sometimes not reached(especially
if the set has been set up for ideal DVD playback).
In this case, the user’s own taste is the main de-
termining factor in finding the right compromise
between the two sources.
This is how you can gradually find the best volume
for the subwoofer:
We do not recommend selecting an automatic
setting for the subwoofer using the integrated
calibration computer (if the receiver has such)
but rather setting the subwoofer in the bass/
speaker setup to a high value between +8 and
+12 dB (around setting “55” on the subwoofer).
This guarantees operation of the auto on/standby
mode; then you can determine the ideal level for
the subwoofer by carrying out listening tests.
Subwoofer remote control
Volume
This sets the subwoofer’s volume. Increase the
volume using the “+” button and decrease it
using the “–” button.
Frequency
Here you can align the subwoofer’s cut-off fre-
quency with the satellite speakers. For operation
on the AV receiver press the “140 Hz” button. The
display on the front of the subwoofer then shows
“14”.

You connect your mono-cinch cable(possibly with a
Y-adapter) from the sub out of the AV receiver here.
 Line Out
Here you can connect an extra subwoofer in or-
der to generate additional bass sound or balance
your room resonance.
 Power Function(Auto)
When switched to “ON”, the subwoofer is perma-
nently on. If you set the switch to “AUTO ON”, the
subwoofer will switch on automatically when it
receives a signal.If it receives no signal,it switches
itself off after about 20 minutes.
 Phase
Here you set the subwoofer’s phase in relation to
your front and centre speakers. If the subwoofer
is set up in the grey area of the drawing on Page 8,
set the phase to “0°”, otherwise to “180°”.
 High Level Input/Output
These sockets are used to connect the subwoo-
fer to older stereo amplifiers/surround receivers
that do not have a subwoofer output. These con-
nections are not used for multichannel AV recei-
vers with a sub out.

normally “11”. The “Frequency” diode lights up .
By pressing the “Frequency” button, you can skip
through the four different presets for the cut-off
frequency: “05” - “08” - “11” - “14”.
 Display and operating diodes
If the subwoofer is switched off at the power
mains switch , no operating diodes light on the
screen. If the subwoofer is switched on at the
main power switch , two small operating diodes
light up red on the screen depending on the set-
ting of the power function slide control . If the
subwoofer is in standby mode = power function
“AUTO ON”, the two operating diodes light on
the screen. If the subwoofer is then switched on,
the screen shows the programmed cut-off fre-
quency. If the subwoofer switches off after about
20 minutes because it has not received a signal,
the two small diodes on the screen light up again.
If the subwoofer is switched to ongoing operation
= Power function “ON” the screen displays the
programmed cut-off frequency.

Problems and solutions · Cleaning
Cleaning
To make sure you are able to enjoy your product
from Lautsprecher Teufel for a long time, please
note the following tips:
Do not expose the casing to direct sunlight. Avo-
id extreme temperature differences and protect
your speakers from moisture. When cleaning the
speaker, only use a slightly damp or dry cloth.
Avoid using materials that contain alcohol or are
abrasive. Remove dust from the membrane very
carefully with a dry cloth.
The subwoofer doesn’t play
light up, reduce the subwoofer volume to “00”,
remove the subwoofer cinch cable from the am-
plifier, turn the volume up carefully and touch the
cinch thermal resistor of the cinch cable (inside)
with your finger. If you can hear buzzing or crack-
ling, the defect is in the amplifier or its settings. If
the subwoofer remains silent in both cases, please
contact our service department.
The subwoofer buzzes
These buzzing noises may be produced by con-
nected appliances or faults in the power net-
work. Excessive buzzing usually has the following
causes:
1. The subwoofer is connected to a different
power circuit from the rest of the equip-
ment. Ensure that all linked appliances are
connected to a single power circuit or plug.
2. The aerial connected to the equipment or
TV has a different ground potential to the
plug. To test this, simply remove all aerial
cables from the wall socket. If the inter-
ference stops, you need a sheath current
filter (available for around Euro 5–10 from
electronics retailers). It is inserted bet-
ween the aerial socket and the TV or recei-
ver.
3. A separately purchased mains filter, to
which all appliances must be connected,
may be useful in eliminating the interfe-
rence.
4. Occasionally, a multiple plug strip proves to
be responsible for creating buzzing noises.
To test this, disconnect the plug strip and
plug the subwoofer’s mains plug directly into
a wall socket.
5. You can also try turning the mains plug
around and inserting it into the socket the
other way up, inasmuch as your mains plug/
socket allows this.
6. In order to better localise the cause of the
buzzing, check whether the subwoofer ope-
rates without buzzing on a power circuit in
another room. In addition, try disconnecting
the cinch connection from the subwoofer to
the receiver in order to exclude the influence
of connected components.
The subwoofer does not switch on automati-
cally when in “Auto ON” mode.
Some AV receivers issue the bass signals via the
subwoofer pre-amplifier output so quietly that
the subwoofer does not start automatically, as
the weak signal is not interpreted as a switch-on
request. To make sure the subwoofer switches on
and off correctly in auto mode, we recommend
turning the level control on the subwoofer only to
“55” and increasing the output level for the sub in
the receiver’s speaker set-up – sometimes up to
the maximum (+10 dB or +12 dB). The subwoofer
should then work perfectly. If not, you can change
the setting to permanently “On”.
The subwoofer reacts to the remote control of
another appliance.
As there are no fundamental regulations on the
distribution of frequencies, each manufacturer
can work with the code of its choice. Unfortuna-
tely, the fact that there may be occasional cross-
overs in individual cases cannot be prevented.
This is, however, not a fault in the subwoofer. If
there are incompatibilities, you can try to cover
the subwoofer’s receiving diode with opaque
adhesive tape. If, however, you have the freedom
to choose another location and can locate the
subwoofer outside the range of the receiver’s re-
mote control (i.e. not right next to the receiver)
this may reduce this problem, as the reception
spectra may then no longer overlap.

Glossar
Active subwoofer
Speaker for bass playback, with integrated amplifier. Very deep
frequencies can only be played back with a large-volume spea-
ker. To make sure that the front speakers can be kept as com-
pact as possible, a separate subwoofer is used for bass tones. It
can be located unobtrusively in the living room: for instance,
behind the sofa or under a side table. The cut-off frequency
between the front speakers and the subwoofer depends on the
components used but is usually between 50 and 120 Hertz.
Auto On/Off function
The Auto On/Off function switches the subwoofer on as soon as
a signal is detected and off again a certain time after the last
signal was transferred(around 20 minutes).
Centre
Central speaker in the home cinema system. All dialogues are
played back via the centre. Therefore, good voice playback capa-
bility is essential for the centre.
Cinema Set
All Teufel speaker systems that are supplied with three direct
front speakers and dipole effect speakers are also called a Ci-
nema Set. In contrast, five direct speakers are called Concert
Sets.
Concert Set
All Teufel speaker systems with five direct satellites are called
Concert Sets. In contrast, Cinema Sets have three direct front
speakers and a dipole rear speaker.
Dipole
Dipole speakers emit sound in two directions. They are there-
fore ideal rear speakers for your home cinema because their
emission characteristics imitate the speaker arrangement in
a commercial cinema. Cinemas always use multiple speakers for
the rear channels and their sound is distributed throughout
the whole room. Dipoles have been designed to emit sound indi-
rectly into the room (i.e. not locatable), which is different from
direct emitters(see below).
Direct emitters
Direct emitters are conventional speakers that transport sound
to the listener in a direct line. In the home cinema, direct emit-
ters are used generally to play back the three front channels; in
Concert Sets they are also located to the rear.
Dolby Digital/DTS Decoder
Electronic switching to divide up the digital multichannel si-
gnals from the DVD into up to seven individual signals.
Dolby Digital and DTS are two different sound formats, so two
different decoders are also required. AV receivers, DVD players
or corresponding sound cards usually have both decoders.
Frequency/cut-off frequency
This is where you stipulate the frequency used for playing back
sounds from the satellites or subwoofer. If, for example, you set
a cut-off frequency of 120 Hz, all frequencies above 120 Hz are
emitted by the satellites, frequencies under 120 Hz are played
by the subwoofer.
Level
The level controller on the subwoofer is used to adjust the vo-
lume. For perfect playback, all speaker channels – incl. the sub-
woofer – should be set such that the signals from the individual
speakers can be heard equally loudly at the listening location.
Phase
With the phase controller, you can adjust the subwoofer to the
satellites such that the speaker membranes vibrate in the same
direction in the cut-off frequency range. If the phase is set in-
correctly, the bass may be weakened or cancelled. If the sub-
woofer is located between the front speakers we recommend 0°,
for a position close to the listening location 180°. If the subwoo-
fer is in another location, the“180°” setting can balance out the
reduced bass playback. Set the phase controller appropriately
to get the strongest bass playback.
Rear speaker
Effects and atmospheric sounds are played back via the rear
speakers (either ĕ dipoles or ĕ direct emitters). This gives a
greater spatial feel when playing back films and music.
Sub Out
Output on the receiver/amplifier to connect an active subwoo-
fer using a mono-cinch cable.
5.1/7.1 pre out
Pre-amplifier output on the receiver or output on the DVD pla-
yer. One analogue signal is provided for each channel via cinch
connection.
6.1/7.1 technology
Surround sound procedure that, in addition to the left and right
rear channel (and the relevant speakers), also uses a centrally
played back rear channel. Depending on the sound format, this
“rear centre” is embedded in the stereo signals for the left and
right rear channel(“matrixed”) and extracted for playback(e.g.
for THX® Surround EX, Dolby Digital EX) or transferred as an in-
dependent signal. Instead of the dominant 5.1 technology, these
are therefore 6.1 sound formats. In practice, it has proven to
be beneficial for the sound to allow the rear centre to be pla-
yed back by two centrally located rear speakers. AV technology
equipped with the necessary amplifiers and connections is the-
refore called “7.1” although it only plays back a 6.1 signal.
